Made a DVD in DVD-lab, and the video jerks a lot.

[mattscholey]

Hi,

I'm using the trial version of DVD Lab (soon to be the full version if I get this problem sorted out). I've made menus, added a 45min video, and burnt it to DVD no problem. The problem comes when I play back the DVD (on both my DVD player and PC).

At some (not all) points where the camera moves about a lot (zooming or panning - I don't mean shake) the video starks to get very jerky (as if it was on a low frame rate), although the audio stays smooth. This problem does not occur in the encoded MPEG file on the PC, but only when I play it back, so I assume something must have gone wrong in the burning process.

Also, the problem starts off bad but improves as the video goes on.

Thanks in advance for your help,
Matt

A week and a bit later, and still no help . If anyones got any idea at all to what could be causing it, I would really appreciate it, even if you can't think of a solution. I'm now looking back into other DVD authoring programs, which is shame, because DVD Lab was great to use.

Any ideas at all, then please post.
Thanks,
Matt

You may have already tried this, or thought of this, but could it be your DVD media? Or the DVD media brand? And have you burnt this on a DVD(-+) R, or RW? I know my DVD player (for some unknown reason) will play DVD+R just fine, but sometimes it has weird problems with RW. Just a thought...

Always try the simplest thing first is my thought

Have you tried playing it off your hard drive? I had a problem with jerky video playing off DVD and it turned out I just didn't have DMA enabled on my DVD-ROM drive after reinstalling Windows. Though if you say it is doing that on your DVD player, then that probably isn't it. I'd certainly concur with j1d10t -- try different media. Also, try authoring small video clips and see if you get the same problem. Try authoring such smaller clips in DVD-lab and something basic to compare against, like IfoEdit.

Another thing I thought of is maybe the field order is incorrect for the MPEG - it would play fine on your computer (because your computer monitor is progressive), but would appear "jerky" or "jumpy" on your TV because it is interlaced.

How was the video encoded? The PC playback can be very deceptive on a lot of errors, such as field order, maximum bitrate, aspect ratio and resolution, color saturation, brightness, etc. About all the PC tells you is that you have a valid file.

Have you tried any other Authoring and burning programs? Have you ever made a video which played correctly? Tried any other DVD players?

My guess would be your problem is field order, or perhaps max bitrate settings.

Ok.

Playing MPEG on the PC is fine.
Playing DVD on PC caused problem.
Playing DVD on DVD player caused problem.

Packard Bell DVD+R's used. They're all I have at the moment, so can't try another one immediately.

My DVD-lab trial is over, so I'll have to try another program. If it works in that, I'll probably stick with it.

Thanks for all your help - it's been supurb.

I'm new to this, but I was having the same problem, especially with quick movement or pans (I'm working on a lot of sports videos captured from VHS). Someone suggested that when you're ready to burn to disk, make sure that on your settings you have the frame type set to field order B. (Your choice are Frame Based, Field Order A or Field Order B).

I'm using Ulead Video Studio 7, so I'm not sure if all programs give you this option. Like I said I'm new to this and not exactly sure what it means (something to do with progressive scan vs. interlaced), but this solved my problem.

Sorry if my terminology is not exactly correct, but hope this helps.

Had the same problem initially, I use Pemier to encode but the mainstay is to ensure that the "bitrate" settings are correct, set them to the Max to ensure that the quality is ok, run it of to a dvdrw until you are satisfied. When encoding select interlaced and not progressive.

I do not think though that these options are available on DV Lab, you might try another program to encode and just use DV Lab to auther and mux the files, its encoder is not very good, then use nero to burn the disc.
